People holding down full-time jobs are still unable to pay for the roof over their heads, show disappointing new figures.

The proportion of households having to claim housing benefit despite being in work has doubled from 11% in November 2008 to 22% in August 2014, according to research from the National Housing Federation.

Why? The National Housing Federation believes this is due to the recession's (and post-recession) unique mix of stagnant wages, high housing costs and decreasing affordability.

The majority of new housing benefit claimants are "middle class"

Of the extra people who have come on housing benefit since the start of the recession: two-thirds of them count as middle-income households, with a salary of between £20,000 and £30,000. That's an increase of 350,000 households in the past six years.

It means every month since the beginning of the recession, an average of 5,000 middle-income households have been forced to claim housing benefits.
